By user terminal to the reverse data transmission course of system, each user terminal can be according to the counter actuation blt (RAB of system forward transmission, Reverse Activity Bit) indicates, and raise or reduce the reverse data transmission rate of self according to the transition probability table that system forward issues.
See also Fig. 1, this figure is at present in CDMA 1X EV-DO network system, and user terminal raises or reduce the process schematic diagram of self transmitted power; Wherein oppositely to adjust the detailed process of self transmission rate as follows for the RAB indication that sends according to system forward of user terminal:
User terminal can carry out the adjustment of reverse transmission rate automatically based on the RAB indication that activates fan section forward broadcasting;
Generally speaking, system is when self bearing load is heavier, and it is 1 indication information that forward direction is sent RAB set; When self bearing load was light, it was 0 indication information that forward direction is sent RAB set;
Wherein user terminal is when RAB=1, and (its probability q adopts default value by base station sets or by terminal, can be reduced to transmission rate 153.6Kbps * q by transmission rate 153.6Kbps as user terminal among Fig. 1 will to reduce transmission rate with probability q
4=76.8Kbps); If the reverse transmission rate of user terminal has been lower than 9.6Kbps, will no longer reduce;
User terminal is when RAB=0, and (its Probability p adopts default value by base station sets or by terminal, can be by being transferred to transmission rate 9.6Kbps * p1=19.2Kbps) on the transmission rate 9.6Kbps as user terminal among Fig. 1 will to raise transmission rate with Probability p; If the reverse transmission rate of user terminal has been higher than maximum constraints speed 153.6Kbps, will no longer raise; Simultaneously, if the back emitted underpower of user terminal also will no longer raise.
To sum up, at present in CDMA 1X EV-DO network system, after setting up the calling connection between user terminal and the system, be to decide the forward data transmission rate according to signal strength signal intensity maximum in the signal strength signal intensity of each user terminal to send up by system, simultaneously in order to reach the maximization that forward direction sends bandwidth throughput, can be according to the reverse Reverse Activity (RA that sends of user terminal, Reverse Activity) indication, system bearing load and and user terminal between message transmission rate between reach an equilibrium.But this data rate transport mode can cause the bad relatively user terminal of channel condition (promptly for other user terminals, the user that signal strength signal intensity is lower) message transmission rate is very low, when serious even can go offline, so just can't realize providing assurable message transmission rate to unique user, also just can't satisfy the demand of user to the part service, applied for that as some the user of banking wishes to adopt guaranteed special line speed to be used for exchanges data, operation such as finish that ATM withdraws the money.

Embodiment
The implementation method of the individual line subscriber that the present invention proposes will at first can provide assurable special line speed to the certain user, and then deciding forward direction transmission rate to non-individual line subscriber according to the signal strength signal intensity of other non-individual line subscriber terminal to report, the throughput that makes forward direction send bandwidth arrives maximization as far as possible; Simultaneously also will be according to the reverse special line speed of individual line subscriber application, transition probability table by system's indication, raise the reverse special line speed of the reverse transmission rate of self to its application, and other non-individual line subscribers are issued RAB indication, make non-individual line subscriber raise or reduce the reverse transmission rate of self, thus be implemented in the system bearing load and and the message transmission rate of user terminal between reach an equilibrium.
Below in conjunction with each accompanying drawing, the embodiment of the implementation method of individual line subscriber of the present invention is explained in detail.See also Fig. 2, this figure is the main realization principle flow chart of the implementation method of individual line subscriber of the present invention, and in CDMA 1X EV-DO mobile communication system, the main implementation procedure of this method comprises:
Step S10 is provided with the required forward direction special line speed of individual line subscriber; This mainly is to enjoy which kind of data communication service according to user's actual needs, and corresponding forward direction special line speed is set;
Step S20, obtain data rate control (DRC) value of individual line subscriber present position: can be by the operating position of analog subscriber in the relevant position, record the user receives forward signal in this position intensity level, try to achieve the DRC value of user present position according to the intensity level of this forward signal;
Step S30 with the forward direction special line speed of user applies among the step S10 DRC value divided by the individual line subscriber present position that records among the step S20, thereby is met the forward direction sending time slots of this user's forward direction special line speed and the ratio that forward direction sends total time slot;
As above, because in CDMA 1X EV-DO mobile communication system, system forward adopts the time division multiple access structure, on the occupation proportion of the present user of priority final body to resource of user's priority and business, just on the occupation proportion to time interval resource.Therefore, in CDMA 1X EV-DO mobile communication system, if individual line subscriber is wished the special line speed obtain contracting, under the specific DRC situation in self present position, must take forward direction and send enough timeslot numbers in total time slot, could guarantee the forward direction special line speed that obtains contracting.
Wherein mentioned here individual line subscriber can be the fixed-line subscriber in the CDMA 1X EV-DO mobile communication system (referring to the relatively-stationary user of mobile station in position) or mobile subscriber (refer to can arbitrarily move user of mobile station).Wherein for some fixed-line subscriber, its DRC value is relatively-stationary, if so before individual line subscriber is opened an account, wireless environment to the individual line subscriber present position is measured, and just can predict take (the forward direction sending time slots numbers of needs) that when satisfying this user's special line speed forward direction sent resource.
See also Fig. 3, this figure is in the implementation method of individual line subscriber of the present invention, the forward direction sending time slots schematic diagram that will take when the user will enjoy special line speed; Theoretical research shows: each individual line subscriber equals the DRC value of the special line speed of individual line subscriber divided by the user present position to the occupation proportion (promptly forward direction being sent the occupation proportion of total time slot) of forward direction resource;
Suppose (a) among Fig. 3: the DRC=153.6Kbps of individual line subscriber present position, the actual special line speed=38.4Kbps of individual line subscriber application, when then this individual line subscriber is enjoyed its signatory special line speed, take the ratio=38.4/153.6=1/4 between the number of forward direction sending time slots and the number that forward direction sends total time slot; As there being a time slot to be used for specially sending data in per 4 time slots among the figure into this individual line subscriber forward direction;
Suppose (b) among Fig. 3: the DRC=153.6Kbps of individual line subscriber present position, the actual special line speed=76.8Kbps of individual line subscriber application, when then this individual line subscriber is enjoyed its signatory special line speed, take the ratio=76.8/153.6=1/2 between the number of forward direction sending time slots and the number that forward direction sends total time slot; As there being 2 time slots to be used for specially sending data in per 4 time slots among the figure into this individual line subscriber forward direction;
Suppose (c) among Fig. 3: the DRC=153.6Kbps of individual line subscriber present position, the actual special line speed=115.2Kbps of individual line subscriber application, when then this individual line subscriber is enjoyed its signatory special line speed, take the ratio=115.2/153.6=3/4 between the number of forward direction sending time slots and the number that forward direction sends total time slot; As there being 3 time slots to be used for specially sending data in per 4 time slots among the figure into this individual line subscriber forward direction;
Suppose (d) among Fig. 3: the DRC=153.6Kbps of individual line subscriber present position, the actual special line speed=153.6Kbps of individual line subscriber application, when then this individual line subscriber is enjoyed its signatory special line speed, take the ratio=153.6/153.6=1 between the number of forward direction sending time slots and the number that forward direction sends total time slot; All will be used for specially sending data as time slots all among the figure into this individual line subscriber forward direction.
Step S40, system is according to the ratio of being asked among the step S30, utilize forward direction to send corresponding time slot in total time slot provides its application for individual line subscriber forward direction special line speed, as mentioned above, if trying to achieve described ratio according to the DRC of the special line speed of user applies and user present position is 1/2, then forward direction can be sent that half time slot in total time slot is used for be that this individual line subscriber forward direction sends data in system, reaches the forward direction special line speed of its application.
Wherein system also will consider following process when forward direction special line speed is provided for individual line subscriber:
According to the ratio that above-mentioned steps S30 is asked for, be calculated as and satisfy the number that all individual line subscriber forward direction special line speed will limit non-individual line subscriber access;
According to above-mentioned non-individual line subscriber access number of trying to achieve, system inserts by the non-individual line subscriber of the described number of restriction, is reached for the purpose that all individual line subscribers provide the forward direction special line speed of its application then.
Because the implementation method of individual line subscriber of the present invention need be on the basis of original system resource access control, guarantee the access at any time of individual line subscriber, and require after individual line subscriber inserts, can to guarantee that this user can obtain the forward direction special line speed of self application, therefore just need come domestic consumer's number that system permits inserting is limited to the situation that takies that system forward sends resource, can be in rational state with the carry load that guarantees system according to individual line subscriber.
Because consider individual line subscriber taking to the system forward resource, can try to achieve corresponding D RC value by the wireless environment that obtains the individual line subscriber present position, and calculate the special line speed that individual line subscriber will be enjoyed its application in conjunction with the special line speed of the actual application of individual line subscriber, can the actual ratio situation that will take forward direction transmission resource decide this individual line subscriber obtain the actual special line speed of its application according to the ratio of being asked for then.Can satisfy in system under the situation of the actual special line rate requirement of individual line subscriber, then the forward direction resource occupation that adding brought that also will calculate an individual line subscriber will limit the adding of how many other non-individual line subscribers (being domestic consumer), and promptly an individual line subscriber will be equivalent to several non-individual line subscribers taking the forward direction sending time slots to taking of forward direction sending time slots; For example: in a sub-district, generally have 30 users forward direction transmission resource of using system simultaneously, if in this sub-district, an individual line subscriber is enjoyed the forward direction special line speed of its application, send 1/2 of resource with taking forward direction, then remain forward direction transmission resource and can support that the number of non-individual line subscriber access is exactly 30 * (1-0.5)=15, be i.e. the adding that adds 15 domestic consumers of affiliation restriction of this individual line subscriber.
Because for individual line subscriber, if such user's channel condition is relatively poor, will take forward direction more or even that system is difficult to bear and send resource, therefore it is relatively stable to be limited to this user present position in a period of time to such user's support, promptly before opening an account, individual line subscriber needs it is measured, the DRC that guarantees the user present position satisfies when opening an account demand and just can open an account, be that system will will reach its forward direction special line speed according to above-mentioned individual line subscriber of trying to achieve, forward direction sending time slots that takies and forward direction send the ratio between total time slot, and judging whether to provide forward direction special line rate service for this individual line subscriber.What is called guarantees that the DRC of user present position satisfies the demand of opening an account and is meant that the DRC value of user present position should be more than N times (N＞=1) of forward direction special line speed that this individual line subscriber will be applied for, require during measurement can reach the forward direction special line rate requirement that it will be applied for to user's the highest forward direction transmission rate, taking the ratio that forward direction sends resource according to aforementioned individual line subscriber like this is the DRC value of the forward direction special line speed of its application divided by the user present position, can guarantee that just individual line subscriber takies the ratio that forward direction sends resource and can not surpass 1, to guarantee that the whole system forward direction sends that resource is unlikely excessively to be depleted on the individual line subscriber, guarantees other users' access.
Simultaneously, individual line subscriber may be because of the variation of wireless environment in prolonged application, cause its forward direction special line speed to get a desired effect, at this moment just need carry out the adjustment of antenna, when system can't satisfy the special line speed of individual line subscriber, can stop to be its service, it is provided under the situation that can provide again the special line rate service is provided.
Because the implementation method of individual line subscriber of the present invention will at first be guaranteed the access of individual line subscriber, therefore just require the base station of system side can pass through air interface resource priority scheduling individual line subscriber, guarantee that wherein individual line subscriber can preferentially be scheduled for, can be by realizing with a weighted value for the DRC of individual line subscriber present position is on duty.Because in the scheduling process of base station to individual line subscriber, on duty to the DRC of individual line subscriber present position with a weighted value N, be equal to the DRC value that makes the individual line subscriber present position and raise N doubly, so just can guarantee that individual line subscriber can preferentially be arrived by base station scheduling.In like manner, if for the DRC of individual line subscriber present position multiply by enough big weighted value, can guarantee that then individual line subscriber can be arrived by base station scheduling.Certainly, also can guarantee that individual line subscriber can be arrived by the air interface resource priority scheduling by the base station, repeats no more here by other scheduling strategies.
Simultaneously, the special line speed that surpasses its application for the forward direction transmission rate of avoiding individual line subscriber, system can realize by the forward direction transmission rate of individual line subscriber is carried out rate limit, promptly can carry out Control for Speed Limitation to the forward direction transmission rate of individual line subscriber by network side (as wireless access network, core net or IP network etc.), to guarantee can not surpass the forward direction transmission rate of individual line subscriber the forward direction special line speed of its application, the forward direction of avoiding individual line subscriber excessively to take system sends resource.
For satisfying the requirement of some data service, when being provided with the required forward direction special line speed of individual line subscriber, the required reverse special line speed of user to be set also; So that the reverse transition probability tables that individual line subscriber can be provided with according to system, raise the reverse transmission rate of self, and when being transferred to the reverse special line speed of setting, remain on this reverse special line speed last.Be zero to realize wherein for realizing that individual line subscriber can be provided with rise probability after arriving the required reverse special line speed of this individual line subscriber in the reverse transition probability tables by system in the reverse transmission rate that raises self the mode on this reverse special line speed of remaining on during to the reverse special line speed of its application; Also can be when the reverse transmission rate that detects individual line subscriber arrives the reverse special line speed of this that be provided with by system, realize to individual line subscriber transmission rate limitation signaling (Rate_Limit signaling), thereby the reverse transmission rate that limits individual line subscriber can not surpass the reverse special line speed of its application, to avoid excessive occupying system resources.
Wherein, the management that oppositely sends resource is that the transmitting power by the control user terminal guarantees individual line subscriber under certain reverse special line speed, what the information of its transmission can be by correct demodulation.From practical application, this power control effect is gratifying substantially, promptly can guarantee no matter individual line subscriber is how far (the normal covering down) apart from the distance of base station by the power control mode, the user of identical reverse transmission rate is identical (may have fluctuation in the power control process, can ignore herein) to the interference of base station basically; Individual line subscriber is to other users' interference and also only relevant with the reverse transmission rate of individual line subscriber and current system total bearing load to the contribution of base station reverse bearing load.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
